    on 572 bbc, raising the comp from 9.7-1 to 11.7-1, hp incre

    what would increasing the compression ratio from 9.7-1 to 11.7-1, or around 2 comp points higher, do for hp increase. Just how much difference would it make ?

    It would raise the torque quite a bit allowing you to use a larger cam which would add a substantial amount of power,to know the exact amount would require before and after dyno runs.Bill
